摘要: 在对天水地区断裂活动性的实地调查和断裂带氡气含量测试的基础上,对研究区内断裂的活动性进行了分析评价分级,分析了地质灾害的发育与分布特征,研究了断裂活动性与地质灾害发育程度之间的关系。研究表明,研究区断裂活动性与地质灾害的发育程度之间有着密切的联系,断裂活动是本区地质灾害的主要影响因素之一。Abstract: This paper presents the investigation of the fault activities and the radon contents in faults in Tianhui area,Shanxi Province.The fault activities are evaluated and classified.The characteristics of geological hazards in Tianshui area are examined.The relationship between the fault activity and the degree of geological hazard is investigated in detail.The results show that the fault activity and the geological hazard degree are closely related,and the fault activity is one of the main factors that controls geological hazards in Tianshui area.
